NuSTAR is to be launched from a Pegasus XL rocket carried by an Orbital Science Corp. L-1011 "Stargazer" plane. It will orbit at 550 km above Earth's surface. A week after launch, NuSTAR will deploy its 10 meter boom , which allows the telescope to focus X-rays and capture images that will help scientists survey black holes in other galaxies, study the black hole at the heart of the Milky Way, and study supernovae to discover hoe atomic elements are formed."
